You are right Carsten: in my .emacs file I have put, since long, the
following lines of command about longlines (following a recommendation found
on the Internet and so far I have been perfectly happy with this):

;;LONGLINES:
(autoload 'longlines-mode
    "longlines.el"
     "Minor mode for automatically wrapping long lines." t)


Now, just 2 questions:

1) should I disable the setting about longlines mode in my .emacs file in
order to solve the problem with the export from .org to latex? Would it be
enough?

AND about your recommendation to switch to Emacs 23

2) I use an old version  of CarbonEmacs for MAC OS X 10.3 Panther 2007 and
for using the new 2009 version of CarbonEmacs (which requires Leopard) I
should say farewell to my G4 Ibook and buy another computer. So: is there
another way to switch to Emacs 23?

Thank you for your kind help.

best wishes

pierfranco
